SPECTACLE-MOUNTING.

To all whom it may concern:

Be it known that I, GUs'rAv A. BADRiLa.

, spectacles or eyeglasses of the rimless t-ype.

The object ot theginvention is to produce a simple, inexpensive, compact, and rigid construction for connecting the bridge of a spectacle or eye-glass-mounting vwith the portion of. the mounting which is directly attached to the lens, and to this end the invention consists in the construction hereinafter described, as it is defined in the succeeding claims.

In the accompanying drawings Figure 1 is a front-elevation, on a greatly enlarged scale., ot' a portion of a spectacle-mounting embodying the present invention, the draw ing showing the lens-straps and one end of the bridge in vertical section; and Fig. 2 is a perspective view of the same parts, with the end of the bridge detached from, but ready for connection with, the rest of the mounting.

In the drawings the inner end of one of the lenses 3 is shown, together with one end ot the bridge 4. These parts may be of any ordinary or suitable form, except that the extremity 5 of the bridge is horizontally disposed, as shown in Fig. 2.

The part of the mounting which is directly secured to the inner end of the lens consists of a member 6 which may conveniently be formed of sheet-metal, and which is bent into U-shape, in horizontal section, so as to provide lens-clips 7 ofordinary form. These lens-clips are secured to the lens by means of a screw 8 in thel ordinary manner.

The invention resides particularly in the manner in which the bridge is secured tothe member t1. forated or slotted so as to form a recess e.\' tending horizontally across the. edge of the lens. The extren'iity 5 of the bridge is seated in this recess or slot and rigidly secured therein. 'The bridge and the meinber are preferabl)Y soldered together, but for additional security, and also to assist in the assembling of the mounting, the parts are formed to have an interlocking engagement. 'lo this end the upper and lower edges ot the slot iii the member U are beveled to form Specicaton o! Letters Patent.

tongues 9, and the extremity 5 of the bridge is provided with slots 10 in its upper and Alower surfaces which interlock `w i.tli-the tongues t). This arrangement permits the extremity 5 to slide longitudinally into engagement with the member 6, but limits the parts to such endwi'se' movement, thus greatly strengthening the construction. This inerlocking engagement facilitates the assemblage of the parts of the mounting, since it holds the parts temporarily in proper rela` tive position while they are being soldered together.

In the drawings the slot inthe member 6v is shown as extending into the lens-clips for the sake of light-ness, butthis is not essential to the invention. The usual lens-straps 11 are provided, these being conveniently formed integral with the other parts of the m'ember 6.

It will be noted that., owing to the formation of the slot in the member 6, the amount of metal comprised in the mounting is somewhat reduced, while at the same time the construction is strengthened, since the area of the contacting surfaces between the parts is increased, thus atording greater security in the soldered joint. It is also a feature of value that when the extremity of the bridge is thus inserted in the slot or recess, it lies substantially flush with the inner surface of the member (3, thus producing a neat and compact appearance. 4

While the construction just described is designed particularly for ilse in spectaclen'iountings, it will be obvious that it may also be applied to eyeglass-mountings of the type in which a rigid bridge is employed in connection with adjustable nose-clamps thereon, and my invention is not, therefore, limited to use in spectacle-mountings alone.

I claim 1*- 1. In a spectacle-mounting, the combination of a slieetlmetal member formed with a central perforation and bent into U-shape in horizontal section so as to provide lens-clips adapted to embrace the inner end of the lens, and a bridge having its extremity horizontally disposed, said extremity belng seated and soldered in said perforation.

2. In a spectacle-mounting, the combination ot' a clip-member formed to embrace the inner end of the lens and provided with means for securing it thereto, said member having a horizontal .slot formed with upper and lower beveled edges, and a bridge havextremity being seated in said slot and having portions engaging and interlocking With said beveled edges.

3. ln a. spectacle-mounting, the combination of a Clip-member formed to embrace l(he inner end ofthe lens and provided With means for securing it thereto, said member being perforated at its inner extremity to l@ form a reoess extending horizontally across the edge of the lens, and a bridge having its extremity horizontally disposed, said extremity being soldered in the perforation in the clip-member with its inner surface substantially flush with the inner surface of the Clip-member. l
